Mixed solution of cerium, europium and neodymium was fed to a column packing silica beads which supported bis(2-ethylhexyl) phosphate. The absorption band formed in the column was pushed out with nitric acid solution, and fractionated using a fraction collector. The concentration data analyzing the fraction shows that, although the separation factor was not so high, the elements were separated each other.

将铈、铕、钕的混合溶液通入负载双（2-乙基己基）磷酸盐的填充硅胶柱中。在柱中形成的吸收带用硝酸溶液挤出，并使用馏分收集器分馏。分析馏分的浓度数据表明，虽然分离因子不是很高，但元素彼此分离。
